Abstract

The invention provides a method for connecting network for a high-security information system. The high-security information system comprises an information processing component, a controlling component, a storing component and a network component. The controlling component comprises a hardware switch; at least one control signal line of the information processing component for carrying out the write operation for the second storing component is connected with the second storing component through the controlling component; when the hardware switch is in the first state, the controlling component cuts off the connection of the control signal and the signal line of the second storing component; and when the hardware switch is in the second state, the controlling component keeps the connection of the control signal and the signal line of the second storing component. The method for connecting network for the high-security information system comprises the following steps: operating the hardware switch to make the hardware switch in the first state; reading the code for the network connection program from the second storing component by the information processing component and storing the code for the network connection program in the storing space of the information processing component; and operating the code for the network connection program in the storing space of the information processing component by the information processing component to connect the network for the high-security information system.
